Waste Rock Pile Design to Lower Closure and Relinquishment Costs

Waste Rock Pile Construction to Lower Closure and Relinquishment Costs

BULC Waste Rock Pile
Earth Systems integrates leading practice AMD management with mine planning by developing a new approach for construction of sulfidic waste rock piles. Referred to as the Base-Up, Layered and Compacted (BULC) construction method, it offers numerous advantages over conventional waste dumping methods. The BULC construction method employs geochemical engineering principles to overcome persistent AMD issues associated with conventional waste rock dumping approaches. The upfront cost of this new approach can be far outweighted by the savings associated with other AMD management and water treatment costs, during the operations and post-closure phases of a mining project.
